I did a few different grades. then applied a very heavy sharpening layer to the same run of clips. one pass of 2px, very strong, then a second pass overlayed with a 1.1px sharpen less prominent than the first. obviously this is too much, but some of the grades dont show it as harsh as others. sharpens nicely IMO - considering how hard I hit the clip.
the first of each bunch of clips is the original file first non sharpened, then sharpened
